USB/BT/BT LE Ultimate includes a VT100/VT220 (WIP) terminal with interactive screen replacing keyboard arrow buttons functionality. It combines functionality of USB- and BT/BT LE Ultimate. Support simultaneous independent terminal emulation and/or file transmission over USB OTG and BT connections with easy realtime terminal switching between these two connections. It can also be used to create direct data bridge between OTG USB COM port and BT virtual COM port or BT LE, allowing to connect third parties devices through BT virtual COM port to devices that have USB port or CLI port like routers
